How a job in Carshalton works
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Carshalton we confirm access and parking beforehand.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Points to plan for in Carshalton
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
